"Say cheese" has produced more bad photographs than any camera ever has. It gives you a mouth shape — teeth bared, cheeks lifted — without the one thing that makes a smile a smile: something behind it.

Everyone knows the result. The photo where you're technically smiling and somehow it still isn't you. Eyes flat, jaw a little clenched, an expression you'd never make in real life because in real life, expressions aren't made — they happen.

This post is about how genuine smiles — the relaxed, teeth-showing, eyes-alive kind — actually get made in photographs. Not with tricks or filters, but with a two-step method any good portrait photographer should be running: one step for the body, one for the face. And a hundred-year-old economics principle explains why the method works so well.
